Group 48 vs 94R Battery: How They Differ (October 2026)
Group 48 and 94R batteries are different sizes, so your vehicle’s required group size decides which one fits. A 94R is longer, and the two Weize AGM options also differ in capacity, reserve capacity and cold cranking amps.

Group 48 and 94R batteries are different sizes, so use your vehicle’s required group size to choose between them. Group 94R is longer; examples from Weize also differ in capacity, reserve capacity and cold cranking amps.
The Weize Group 48 measures 10.94 x 6.89 x 7.48 inches, while the Group 94R measures 12.4 x 6.89 x 7.48 inches. Both are AGM batteries, but their dimensions and ratings are not interchangeable by assumption.
Group 48 vs 94R: what is the main difference?
The main difference is case size: the Group 94R example is 1.46 inches longer than the Group 48 example. Their width and height are the same, but the extra length can affect tray fit and hold-down placement.
Group 48 is also labeled H6, and Group 94R is also labeled H7 on these Weize batteries. These size names help with comparison, but your vehicle’s manual or a trusted fit guide should decide which group to use.
| Feature | Weize Group 48 | Weize Group 94R |
|---|---|---|
| Common alternate label | H6 | H7 |
| Dimensions | 10.94 x 6.89 x 7.48 in | 12.4 x 6.89 x 7.48 in |
| Capacity | 60 Ah | 80 Ah |
| Cold cranking amps | 760 CCA | 850 CCA |
| Reserve capacity | 120 RC | 140 RC |
These figures compare the specific batteries in this guide. They don’t establish that every battery in a group size has the same ratings.
Which battery fits your vehicle?
Choose the group size your vehicle specifies, then check the battery’s dimensions and terminal position. Similar width and height do not make Group 48 and 94R a safe swap.
The Weize Group 48 has tapered terminals, with negative on the left and positive on the right. The Weize Group 94R uses the same stated terminal arrangement, but still requires a longer tray than the Group 48 case.
Before ordering, compare your current battery’s label and measurements with your vehicle manual. Also check the required hold-down, minimum CCA and battery type.
The battery size guide explains how group numbers help identify fit.
If you don’t know the group size, start with how to find the right battery size for your car. Don’t choose a larger group only because it has higher capacity or CCA.
Does a Group 94R provide more power?
The Group 94R example has higher capacity, reserve capacity and CCA than the Group 48 example. Those higher figures may suit a vehicle that calls for them, but they don’t make the 94R an upgrade for every car.
The Weize Group 48 is rated at 60 Ah, 120 RC and 760 CCA. The Weize Group 94R is rated at 80 Ah, 140 RC and 850 CCA.
CCA matters for starting, especially in cold conditions, but you should meet your vehicle manufacturer’s minimum. Use the guide to choosing the right cold cranking amps if you’re comparing batteries with different starting ratings.
Reserve capacity describes how long a fully charged battery can provide a set amount of current under standardized conditions. Learn what the measure means in our battery reserve capacity guide.
Which Group 48 or 94R batteries are worth comparing?
Match the product to your required group size first, then compare its ratings and features. The options below cover both sizes and include another Group 48 AGM choice.
The Weize Group 48 is the more compact choice when your vehicle specifies that size. Its stated dimensions and terminal layout still need to match your tray and connections.
The Weize Group 94R has higher stated capacity, CCA and reserve capacity, along with the longer case. Consider it only where the vehicle calls for Group 94R and the fit checks out.
The ACDelco Gold 48AGM gives Group 48 shoppers another AGM option to compare. Its published dimensions are 11.9 x 7.5 x 7.6 inches, so check them against your battery space and required terminal arrangement.
Can you use an AGM battery in place of another type?
Use the battery type your vehicle requires, or confirm that an AGM replacement is approved. A matching group size by itself does not confirm that a different battery type will work as intended.
Both Weize options are AGM starter batteries intended for vehicles with start-stop systems or higher electrical accessory loads. The ACDelco Gold 48AGM is also an AGM battery.

What should you verify before ordering?
Confirm the required size, battery type, dimensions, terminal position and CCA before you buy. These checks help prevent a battery that fits poorly or fails to meet the vehicle’s requirements.
Measure the old battery and compare its case length, width and height with the replacement. Check the positive and negative positions from the same viewing angle, since a reversed layout can keep cables from reaching safely.
Then verify the minimum CCA, hold-down and any start-stop requirements in the manual. If you’re replacing an aging battery, the guide to car battery replacement covers the steps to plan before buying.
Group 48 vs 94R: which should you choose?
Choose Group 48 when your vehicle specifies Group 48, and Group 94R when it specifies Group 94R. The 94R examples here have higher ratings, but fit and vehicle requirements should lead the decision.
For a Group 48 replacement, compare the Weize and ACDelco options by dimensions, terminal layout and required battery type. For a Group 94R replacement, confirm the longer case fits before weighing its higher stated capacity and CCA.
Start with your manual or vehicle fit guide, then compare the exact battery measurements. The best Group 48 batteries and best Group 94R batteries guides can help you continue comparing within the size your car needs.
Frequently asked questions
Can I replace a Group 48 battery with a 94R?
Only if your vehicle manufacturer allows Group 94R and the longer case, terminals and electrical ratings fit. The Group 94R example here is 12.4 inches long, compared with 10.94 inches for the Group 48 example.
Check your owner’s manual or fit guide before changing group size.
Is Group 48 the same as H6?
Group 48 is commonly paired with the H6 label, as shown by the Weize Group 48 battery. Still, confirm the group size and dimensions for your vehicle, since labels alone do not verify terminal position, hold-down fit or required battery type.
Is Group 94R the same as H7?
Group 94R is commonly paired with H7, as shown by the Weize Group 94R battery. Use your vehicle’s specified group size as the guide, then confirm the case dimensions, terminal layout and minimum cold cranking amps before buying.
Which has more capacity, Group 48 or Group 94R?
The Group 94R example has more capacity: 80 Ah versus 60 Ah for the Group 48 example. That comparison describes these Weize batteries, not every battery in those group sizes, and it does not mean the larger group is approved for your vehicle.
What should I check before buying either battery?
Confirm the required group size, battery type, case dimensions, terminal position and minimum cold cranking amps. Also check the hold-down and charging requirements in your vehicle’s manual.
A battery that fits the tray can still be wrong if its terminals or electrical ratings do not match.
